You do a physics lab experiment on another planet. a small block is released from rest at the top of a long frictionless ramp that is inclined at an angle of 36.9° above the horizontal. you measure that a small block travels a distance 18.0 m down the incline in 5.70 s. what is the value of g, the acceleration due to gravity on this planet?

g= 1.8 m/s²

Explanation:

From conservation of energy we know:

Solving for g with h being the height of the ramp with angle ∅ and length L:

(1)

The velocity v at the bottom of the ramp for a constant acceleration a in a time t is given by:

(2)

Plugging equation 2 in to equation 1:

(3)

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
